Mozilla has unveiled a new feature for its Firefox web browser called “Quarantined Domains,” which will block certain extensions from running on specific websites. In the release notes for Firefox version 115.0, Mozilla explained that the tool will only allow some extensions monitored by Mozilla to function on designated websites due to security concerns.
In a blog post, the company elaborated on the rationale behind this move, stating that while an open ecosystem of add-ons benefits developers, it can also be exploited by threat actors. Mozilla acknowledged that reviews and user reports might not always be sufficient to identify and prevent malicious add-ons.
